Have played all the expansions and I enjoy the neoprene mats and the ability to keep everything in one box. The solo mode is intriguing, I’ve finished with all but 2 heroes gone and I have finished with over 10 wounds…! For those who have played several versions of boss monster—the basic rooms tend to be almost stronger than the advanced rooms due to the +1 damage possibilities (that do not transfer if you build a room on top). Not my favorite expansion—that might be minibosses. But I do like the perks in the big box and was sooo very happy to find a kickstarter edition—I learned about boss monster in June of 2024—so shortly after the kickstarter campaign ended. Thank you so much Bards & Cards—you were very easy to work with and shipped it quickly and made my husband and I very happy! :-)
